Mountain downhill skills introduction
2022-05-22
Mountain downhill sports is abbreviated as DH. Mountain downhill is arguably the most exciting form of mountain biking. Usually refers to the whole process of downhill, the speed can reach 50-80 kilometers per hour, and the terrain is usually more complex and changeable.
The origin of mountain downhill
When it comes to mountain downhill sports, we must start with the birth of mountain biking. It is said that mountain biking originated in the United States. At that time, a group of young people rode their bicycles to seek excitement on the off-road venues of motorcycle races. Slow development becomes an activity. Ordinary off-road sports cannot satisfy young people's psychology of challenging the limit. Some of them started to choose some hillsides or mountains and rush down from above, feeling the thrill of the process. The current known record for mountain biking downhill is hourly 210 km, which was created by an Austrian.
With the continuous improvement of mountain bike manufacturing technology and the development of the suspension system, mountain bikes with large suspension stroke, high body strength, wide tire width and strong grip performance are more suitable for the classification of mountain bikes for mountain downhill. Mountain Bike. In order to withstand the high-strength impact force, the material selected for the downhill frame is mostly high-strength aluminum alloy material, and then high-strength welding technology can be used to make the frame withstand strong impact force. At present, the structure of the frame is generally a multi-link structure with single moving point and multiple moving points. The frame structure of the single point of action is the work of the central connection of the frame and the shock absorber. The disadvantage is that the body will lose the effect of the rear shock when the rear brake is used. The multi-point mountain downhill bike is based on this. Through the cooperation of various power points, the brakes and shock absorbers can work at the same time in complex situations, so as to obtain a faster downhill speed.
With high-strength shock absorbers. It is very different from a normal mountain bike fork. The front fork stroke of ordinary mountain bikes is mostly 80mm or 100mm, while the front fork stroke of mountain downhill bikes is mostly 180mm or 200mm. In order to pursue better passability, long strokes require high strength. So it is also called double shoulder fork.
Therefore, the weight of mountain downhill bikes is also very amazing, usually reaching 20-30kg. And, the gear ratios of this mountain bike designed for mountain downhills are also very high. In order to prevent the chain from falling off and protect the chainrings, a chain protector is specially installed. This particular design is good enough for downhill enthusiasts to tackle all kinds of very rough roads, even cliffs that are several meters deep. It is because of the high demands placed on speeding bikes that downhill mountain bikes are often expensive.
Therefore, many riders who are interested in going downhill will opt for slalom before starting the descent. The English name of the slewing car is Dual Slalom, referred to as DS. This is a car that incorporates downhill elements. Because usually the technology of the slewing car is mainly based on high-speed jumping and turning. Therefore, in order to deal with the impact of landing, shock absorbers with good performance will also be installed, and some shock absorbers will be installed in the front and rear.
The most important point is that mountain downhill bikes are simple in structure and relatively cheap; precisely because of their simple structure, mountain downhill bikes are lighter than off-road bikes, easier to control, and more comfortable to ride. Therefore, many mountain downhill beginners will choose mountain downhill confrontation racing to start practicing.
Introduction of equipment for mountain downhill
Among the enthusiasts involved in mountain downhill bikes, the most recognizable ones are mountain downhill enthusiasts. Because they are always armed to the teeth. This is mainly because the terrain that mountain downhill sports needs to face is complex, and it is not difficult to control speeding on bumpy mountain roads. Therefore, in addition to wearing full helmets, people often wear armor, elbow pads, and knee pads.
The most prominent is the full face helmet they often wear, which protects the head and chin. Most of these are high-tenacity carbon fiber shells with shock-absorbing foam rubber inside. There is a cushioned rubber grille in front of the muzzle, plus a clear transparent front for high visibility. Goggles, these are the best protection for the head, ensuring that the head is not directly hit by hard objects at critical moments.
In addition, the protection of the body is also crucial, and athletes usually wear a well-protected "protective clothing". It generally includes a piece of armor that connects shoulder pads, arm pads, elbow pads, wrist pads, and chest pads, a pair of iron or rubber shell knee pads that reach the calf shin and waistband, and even the inner thighs and hips that rest on the cycling shorts Thick cotton pads provide protection.
Still, we still regularly see reports of incidents involving mountain downhill enthusiasts. After all, this is a sport that pushes the limits. The maneuverability and the terrain to be faced are complex. Therefore, to enter the ranks of mountain downhill masters, you must start with the most basic skills and progress step by step. careless.
Downhill basic skills and tips
When going downhill, don't stare at your wheels all the time, pay more attention to the front, which will help you adjust the speed and cornering action in advance to deal with the impact.
Generally, when going downhill, you should take a standing position at an appropriate time, which is more conducive to the body to absorb the impact from the ground and the lock that cannot be absorbed.
While a friend might tell you to relax your hands when you're just starting to learn downhill, the ancients said it too well, so if you relax too much, you won't be able to handle a sudden shock. Do it The best way is to go with the feel, move with the car, and control the car at the right time.
Use your feet and cushions wisely. Especially when the buttocks leave the seat cushion, it is best to use the relationship between the legs and the seat cushion to control the balance and body posture of the car, and it is more convenient to move the center of gravity when going downhill.
Use the brakes at the right time. Braking can certainly slow you down, but if you brake too hard at the wrong time when you're rushing down at high speed, the consequences can be imagined. If you are traveling in mud, the mud itself already provides some resistance. At this time, it is even more important to keep your focus. If the center of gravity is on the front wheel, you may experience bowing.
Don't dance just to be handsome. The wrong jump timing will only cause you unnecessary trouble, especially when you're about to face a series of thorny roots and rocks.
